To start this critique, this piece is a nice example of what *heavenriver can create in UltraFractal. The rainbow gradient fits in naturally, and that is a hard tash to pull off in the world of fractals wjere one colour usually finds a way to dominate the utter crap out of the rest.
The shapes in the fractal are almost petallike and add to the elegant finish of this fractal.
If I had to point out a flaw, it would be that, no surprise here since it is me writing this, I think that there are spots that are overly saturated and it kinda ruins the feel a little for me. If the colours were dimmed down a little it would be pretty much perfect! But that is just me being a snob.
In conclusion, this is a wonderful fractal. Be sure to check out the rest of her stuff!
